UFC 163’s main card airs live on pay-per-view following prelims on FX and Facebook.

Maia returns to action while hoping to cinch his fourth consecutive win and, likely, the next shot at the welterweight title. Since dropping from 185 to 170 pounds, the submission specialist has won bouts against Dong Hyun Kim, Rick Story and Jon Fitch.

The Fitch victory solidified Maia as a top contender, and while Johny Hendricks currently holds the position of No. 1 contender, the Brazilian could be within a win or two of the same designation.

Koscheck, meanwhile, is badly in need of redemption. The former title challenger has dropped two straight bouts, including a decision to Hendricks and, most recently, a first-round TKO to Robbie Lawler. Prior to that, he had won back-to-back bouts over Matt Hughes and Mike Pierce.

While it may be too early to say Koscheck is in a must-win situation, his relevancy in the division hangs in the balance.

A total of 26 fighters got their chance to shine on Saturday as part of UFC 190 at Rio de Janeiro’s HSBC Arena. Now that UFC 190 is in the books, it’s time to commence MMAjunkie’s “Three Stars” ceremony.

The man known for cranking submissions to the point of injury added eye-gouging to his repertoire. But is the controversy of Rousimar Palhares too essential to his bizarre, awful appeal for his employers to take any meaningful action against him?
